Control interface assembly

Abstract

An interface or throttle control assembly includes a housing and first and second wheel rotatably supported by the housing adjacent to each other. The assembly also includes a pair of tabs, each projecting from a corresponding one of the wheels. The tabs are engagable with each other. The assembly also includes a latch mechanism which mounted on one of the wheels. The latch mechanism is movable to a latched position engaging the other wheel so that the wheels rotate together, and is movable to an unlatched position so that the wheels can be rotated independently of each other.

What is claimed is: 
     
       1. An interface assembly comprising:
 a housing; 
 a first member rotatably supported, about an axis, by the housing; 
 a second member rotatably supported, about the axis, by the housing, the second member being adjacent to the first member; 
 a first tab projecting from and fixed with respect to the first member; 
 a second tab projecting from and fixed with respect to the second member, the second tab being engagable with the first tab; and 
 a latch mechanism mounted on one of the members, the latch mechanism configurable to be in a latched position engaging the other member so that the members move together, and the latch mechanism configurable to be in an unlatched position so that the members move independently of each other, the latch mechanism comprising:
 a first pin projecting from the first member; 
 a second pin projecting from the second member; and 
 a bail pivotally mounted on the first pin, the bail being movable to releasably engage the second pin. 
 
 
     
     
       2. The interface assembly of  claim 1 , wherein:
 the bail comprises a bar having a bore which rotatably receives the first pin and a slot which releasably receives the second pin. 
 
     
     
       3. The interface assembly of  claim 1 , wherein:
 the first pin projects radially from the first member; and 
 the second pin projects radially from the second member. 
 
     
     
       4. The interface assembly of  claim 1 , wherein:
 the first member comprises a wheel; and 
 the second member comprises a wheel. 
 
     
     
       5. The interface assembly of  claim 1 , wherein:
 the first tab overlaps a portion of the second member; and 
 the second tab overlaps a portion of the first member. 
 
     
     
       6. The interface assembly of  claim 1 , wherein:
 the first and second members are rotatably supported by the housing. 
 
     
     
       7. The interface assembly of  claim 6 , wherein:
 the first tab projects radially and axially from the first member; and 
 the second tab projects radially and axially from the second member. 
 
     
     
       8. An interface assembly comprising:
 a housing; 
 a first wheel rotatably supported by the housing; 
 a second wheel supported by the housing adjacent to the first wheel; 
 a first tab projecting radially and axially from the first wheel, the first tab overlapping a portion of an outer surface of the second wheel and being fixed with respect to the first wheel; 
 a second tab projecting radially and axially from the second wheel, the second tab overlapping a portion of an outer surface of the first wheel, the second tab being engagable with the first tab and being fixed with respect to the second wheel; and 
 a latch mechanism mounted on one of the wheels, the latch mechanism configurable to be in a latched position engaging the other wheel so that the wheels rotate together, and the latch mechanism configurable to be in an unlatched position so that the wheels rotate independently of each other, the latch mechanism comprising:
 a first pin projecting from the first wheel; 
 a second pin projecting from the second wheel; and 
 a bail pivotally mounted on the first pin, the bail being movable to releasably engage the second pin. 
 
 
     
     
       9. The interface assembly of  claim 8 , wherein:
 the bail comprises a bar having a bore which rotatably receives the first pin and a slot which releasably receives the second pin. 
 
     
     
       10. The interface assembly of  claim 8 , wherein:
 the first pin projects radially from the first wheel; and 
 the second pin projects radially from the second wheel. 
 
     
     
       11. The interface assembly of  claim 10 , wherein:
 the bail comprises a bar having a bore which rotatably receives the first pin and a slot which releasably receives the second pin.
